said plate 10 in a vertical plane perpendicu- I O spaced relation from the upper surface of the claimsai'ld illustrated by the accompanying drawings, in which 1 i f I Figure 1 is-an elevation of one side of my improved mechanism as assembled for practical use, the elements being shown in'normal 155 or open switch positionand one side of the mechanism housing being removed. Figure 2 is a horizontal section through the showing of Figure 1 eon'the indicated line 2-2 of the latter figure. Figure 3 is an elevation offthe side of my improved mechanism op posite to that shown in Figure 1, the elements being positioned to correspond with the showing fofF igure 1 and'a portion 'of the P mechanism housing being-broken away to dis-e close otherwise concealed construction. Figure 4 is a fragmentary, detail section taken on the indicated line 4+4 of Figure 3, certain elements of the complete mechanism being omitted in favor of simplicity and clarity. 1 Figure 5 is a detail end elevation of certain of the elements employed in'the mechanism. Figure 6 .is al -vertical, detail section anism. I I I p In the construction'of'the improved mechanism as shown, the numeral 10 designates a baseplate on and about which theelements of the mechanism are operatively arranged, said plate preferably being of metal, relatively thin, and of any suitablesize and shape. The plate=10should be positioned in a true vertical plane for successful operation :of the devicescarried thereby andmay besupported in the desired positionin any suitable manner. A-face plate 11 is formed integrally with or permanently secured -to one margin of the plate 10 andextends on both sides of often adj usting'deviceemployedin the mech- I lar to theplaneof: saidbase plate. As shown in Figure 1, a pin 12 is fixed to andprojects perpendicularlyrfrom one side, hereinafter [known as the switch side,;of the plate IO in the upper, forward portion of said plate, the G face plate 11 being considered as defining the forward margin of the base r plate 10, and a bracket 13 is mounted on and for oscillation in a vertical "plane about said pin 12 adjacent the plate 10. f Spring clips 14 rise in 1 bracket 18 to retain and support a conventional mercury-type switch tube in parallel relation with the upper surface of said bracket, said tube 15 being a common and well-known element comprising a sealed con-' terminals and mercury being so arranged.

that when the tube is tilted with its conductor end lower than its plain end the mercury will envelop both of the spaced termimils and complete an electrical circuit through the conductors 16, which circuitvis broken by flow of the mercury away from the terminals when the tube is tilted withits plain end lower than itsconductorend, as illustrated. in Figure 1', For convenience, the conductors 16 are led through binding posts 17 carried by the housing enclosing the mechanism and may be operatively connected with any suitable electrical device: or apparatus and with a sourceof electrical energy in such manner as to permit control of such device or apparatus through the making or breaking of the circuit through the conductors: 16 as determined by the relative position of the tube 15. Fixed to and'in depending relation with the bracket 13, an arm 18 is positioned to swing in spaced parallelism:with the plate 10 as said bracket is rocked about its pivot 12, and a pin 19 is fixed atone: end in the outer end of the arm 18 and extends therefrom in parallel relation with the pin, 12 through an aperture 20 formed inthe plate 10 to terminate in a forwardly-curved free end projecting some distance beyond said plate 10, engagement of the pin 19 with mar- V gins of the aperture 20 defining and limiting the range of oscillation of the bracket 13 and tube 15 between open and closed circuit positions of said tube. A lever 2'1 formed with a forked end 22 is pivoted at 23 to the switch side of the plate 10' with the prongs of its forked end 22 engagingopposite sides of the pin 19, said lever 21 extending downwardly from its pivot 23 to terminate in a forwardly-extending contact. finger .24. A suitable device, such as a spring 25, connects the bracket 13 with the plate. 10in such a manner as to normally yieldingly retain said bracket at one or the other of its limits of oscillation. Reciprocable through a guide 26 on the switch side of the plate 10, a slide bar 27 t is horizontally-disposed adjacent said plate in spaced relation beneath the switch assembly above described, the forward end of said bar 27 merging with a slide rod 28 forming an alined extension of the bar 27, which rpd 28 extends forwardly through a slide aperture in the plate 11 to terminate in a knob 29 spaced forwardly of the said plate 11. The slide assembly 27 28 and 29 is thus positioned and supported for rectilinear reciprocation along the plate 10 and perpendicular to the plate 11 by means of the guide 26 and slide aperture in said latter plate, and

t is normally retained at the forward limit of traversed by a smooth axial bore wherein is receivedan adjustable rod 32. The rod 32 is loosely received in the bore of the cross-head 31 and projects at each end beyond the ends of said cross-head, the lowermost position of said rod being such as to position its upper end beneath and in position to clear the finger 24 of the lever 21, and its uppermost, position being such as to position its upper end above and in engageablerelation with said finger, pins 38 perpendicularly through said rod serving to limit the relative movement between said rod and the crosshead 31. As shown in Figure 6,. an offset pocket 34 is provided on the cross-head 31 in communicationwith the bore thereof, said pocket housing a spring-pressed ball 35 operable to engage suitably positioned notches 36 in the rod 32 and yieldingly hold said rod in the desired relation with said cross-head. The relative position of the rod 32 determines whether oscillation of the switch tube 15 to close the circuit through the conductors 16 is to be accomplished with or without coin control, since with the rod 32 in its lowermost position, as illustrated by full'li'nes in Figure 1, manual reciprocation of the slide assembly 27, 28,. 29 simply, moves the rod 32 as the assembly is moved without bringing said rod into engagement with any of the other elements of the mechanism and permit ting operation of the coin-controlled mechanism hereinafter to be described; on the other hand, when the rod 32 is moved upwardly of the cross-head 31 to the position shown in dotted lines in Figure 1, rearward motion of the slide assembly operates to engage the upper end of the rod 32 against the finger 24; of the lever 21 and swing said lever about its pivot 23, which motion of the lever 21 acts through the fork 22, pin 19 and arm 18 to swing the bracket 13 about its pivot to circuit-closing position of the switch tube 15 carried thereby. Parallel with and above the slide bar 27 a slot 37 is formed in and through the plate 10, said slot extending from the rear margin of said plate across the major portion thereof toward the forward margin, and a slide block 38, H-shaped in cross section', is mounted in and arranged to slide freely along said slot, the parallel legs of the block 38 being thus positioned on opposite sides of the plate 10. On the switch side of the plate 10, the forward end of the block 38 is thickened to form a head 39 opposed to and adapted to be engaged at times by a lug l0 lug 40 to withdraw the one end of a retractilei coil spring 42 connecting said arm 41 with an ear or lug on the plate 11, it being the function of thespring "42 to normally position the block; 38 with its head 39 in'engagement with'the lug 40, and to 4 return said block to normal position after t displacement therefrom! To decrease the speed with which the block 38 is returned under the influence of the spring 42 and to minimize the shock resulting from sudden stopping 'of'said block, a piston 43 is, adjustablyfixed by means of its pistonrod 44 to the upper outer end of the arm 41in osition to be slidingly received within the ore of a rearwardly-opening cylinder 45carried by the plate in axiallytparallel relation with the slot 37, said piston and cylinder thus forming a conventional dash-pot whereby the speed of the block ,38 is decelerated as it approaches itsforward position; through the action of the spring42, As shouldbe readily apparent, inward pressure applied tothe knob 29 acts to move the slide bar 27 rearwardly along the plate 10 against the pressure of the spring ,30, the-block 38 moving simultaneously against, the pressure f of its head 39 with the piston 43 axially of its cylinder 45 release of the pressure on the knob 29. permitting,

the slide bar 27 to be promptlyreturned by its spring 30 while the block 38 follows more slowly as thepiston and cylinder assembly retards theaction of the spring 42. a 1

On the side of the plate 10 opposite to the switch side, shown in Figure 3 and conveniently'designated as the coin side of said plate, suitable plates 46 and spacing blocks i7 are assembled and arranged to form a downwardly and rearwardly directed coin race one side of which is defined by the surface of the platelO. The upper forward end of the coin coin slot 'opening'through the plate 11, said slot being indicated by dotted linesin Figure 3, said race being directed first downwardly along the plate 11, then rearwardly' and downwardly across the plate 10jand finally downwardly and forwardly of the 'platelO to a coin discharge-above the leg of the block 38 adjacent the coin side of said plate, so that a coin inserted through the coin slotfof the plate ll drops and rolls through saidrace to a position of rest wherein it is marginally supported on and above said legofthe block 38 with its plane surfaces parallel with the plate10, as indicated by dotted lines in Fig ure 3, a pin 48 'beingfixed to the plate 10in i of said coin along the block 38. As clearly shown in Figure 4, the rearwar dly-extending.

portion'of the coin race is widened and provided with'a short partition 49 dividing that a portion ofthe race into two coin passages, the

inner of which communicates'with the coin drop wherethrough a coin must pass to be received on the block 38' and the outer of which terminates in-a discharge opening not communicating with the, switch-operating ele-- ments of the mechanism. ()n the outer Wall ofthe plate 46 between; the first coinv'drop and the partition 49 ismounted apermanent magnet 50, so arranged as to attract spurious coins ofmagnetically-susceptible material outof thecoin passage adjacent the plate 10 and into the outer of thepassages defined by the partition 49 whence said spurious coins are discharged clear of the operating elements of the mechanism, the strength of the, magnet 50 being suflicient only to divert said spurious coins and not enough'toarrest such coins in the race. Vertically-disposed in' spa'ced.,straddling relationwiththe'rear portion of the block 38, arock-shaft51 is mounted for rotary oscillation between brackets 52 fixed to and projecting from the coin sideof the plate '10, a radial arm 53 extending for- I wardly and outwardly from the upper end of said lrock-shaftabovethe top plane of the v blcck'38t'o support a needle element 54 in spaced opposition with xthe coin position above said block. [T he needle element 54 is slidingly mounted in a bore of the arm 53- and is yieldingly positioned in ;maximum projection therewith by a leaf spring 55 fixed at one end tothe arm 53land'bearing at its platelO. A curved finger 57 is fixed to the rock-shaft '51and curves rearwardly and inwardly therefrom in overlying relation with a roller 58 carried by the rear end of the block 38, the inner, curved surface of the 1 finger 57 normally contacting the periphery race communicates with a vertlcall'y disp'osed of the roller 58 by virtue of the action of the other end against the base'of the element- 54, p

spring 56 andthus limiting the divergence of the arm 53relative to theplate'lOi When the block 38'i's moved rearw'ardly along the slot 37; the roller 58 acts on the inner curved I 7 surface of the finger 57 to rotate the rockshaft 51 and swing thearm 53 through ashorizontal arc toward the plate 10, driving the point of the needle '54 sharply against the face of a-coin positioned against said' 'plate and above the block 38; Due to the shape of the finger 57, the movement of the arm 53 is rapid and brief,-since as soon as the roller 58 has passed beneathsaid finger thespring' 56 returns the arm 53 and finger 57 to normal position. Should a. valid coin be in position at the lower end of the coin race, thepoint of the needle 54'will: fail to penetrate said coin as the arm 53 is swung inwardly andsaidf needle will yield in the arm 53 against the pressure of the spring 55, the coin remaining in position ready for further operations when the arm 53 is swung away to normal position. However, should a spurious coin of relatively soft material have passed through the race to the block 38, the needle point will penetrate the surface of such spurious coin as the arm 53 is flipped inwardly and take sufficient hold of such coin as will enable it to draw the coin from the block 38 and free of the operating elements of the mechanism. Spurious coins extracted from the mechanism by the needle fall from said needle on theoutward movement of the latter to an inclinedplane 59 whereby they are directed to an opening 60 in the plate 11 for return to the depositor.

On a pin 61 projecting perpendicularly from the coin side of theplate 10 above and forwardly of the forwardend of the block 38 is pivotally mounted one end of a U-shaped bracket 62 disposed with its baseextending in substantially a horizontal plane rearwardly of the pin 61 and in spaced, parallel relation with the plate 10, the jaws of said bracket opening outwardly of and away from said plate, thus mounting saidbracket for oscillation about its pivot 61 through a vertical are parallel with the plate 10; I A disc 63 is mounted for rotation on and carried by the base of the bracket 62 between said base and the surface of the'plate 10. On, a pivot extending radially of the pin 61 between the jaws of the bracket 62 is mounted a rockshaft 64,- said rock-shaft being formed with a depending boss 65 on the lower end whereof a disc 66 is rotatably mounted in a substantially horizontal plane, and is further formed with an outwardly and rearwardly curved arm 67 rising from said rock-shaft above and behind the free end of the pin 19, a spring 68 between and engaging the bracket 62 and arm 67 acting to normally retain said arm in maximum spaced relation with the plate 10.

A lug 69 projecting laterally from the coin race is positioned to engage behind the arm 67 and limit clockwise motion of the assembly above described about the pivot 61. When the operating elements of the mechanism are in coin-receiving position, as illustrated, the arm 67 is at its rearmost position as determined by the lug 69 and the forward end of the block 38 on the coin side of the plate 10 is entered behind the. disc 66, thus swinging the upper end of the arm 67 inwardly toward the plate 10 and behind the pin 19. As the block 38 is movedrearwardly, its forward end is withdrawn from behind the disc 66 and the spring 68 then acts to swing the upper end of the arm 67 away from the plate 10 and into clearing relation with the pin 19, the limit of this motion being determined through contact of the disc 66 with the plate 10. As rearward motion of the block 38 is continued, said block is withdrawn from'beneath the coin position and the coin therein is permitted to drop to a step 79 provided beneath said block and in front of the forward end of the retracted block, which step is fixed to the plate 10 and provided with an upstanding flange 80 spaced from said plate and arranged to steady the coin in upright position on said step. When the pressure applied to the knob 29 is released and the block 38 returns under the action of its spring 42, the forward end of said block engages the periphery of the coin and pushes the latter forward along the plate 10 into engagement with and behind the disc 66, which action swings said disc outwardly from the plate 10 against the pressure of the spring 68 and moves the upper end of the arm 67 inwardly into engaging position behind the pin 19. Further forward travel of the block 38 pushes the coin into marginal engagement with the disc 63, thus lifting said disc and swinging the bracket 62 through an upward are about the pivot 61, consequently moving the upper end of the arm 67 forwardly against the pin 19 and thereby swinging the bracket 13 from open to circuit-closing position of the switch tube 15. In order to pre- Vent introduction of a coin to the operating elements of the mechanism when the block 38 is retracted, a rod 70 is vertically journaled on the. switch side of the plate 10 behind the cylinder 45 and is formed with a forwardlyextending upperend 71 bent to project at times through a hole 72 in the plate 10 and obstruct the coin race and a lower end portion 73 projectingthrough the plate 10 immediately above the'block 38. A spring 74; engages the end 71 of the rod 7 0 to normally position said end 71 in obstructing relation with the coin race and a lug 75 is carried by the block 38 in position to engagethe end portion 73 of the rod 7 O as said block reaches its most forward position and rotate the rod 70 against the pressure of the spring 74 to swing the end 71 out of the coin race and into the position shown in Figure 2, any rearward motion of the block 38 disengaging the lug 75 from the rod portion 73 and permitting the spring 7 4 to act to again obstruct the apparatus or mechanism has functioned to the desired extent a downward pull will be exerted on said rod 77, which pull, it is obvious, will rock the bracket 13 from closed to open circuit position of the switch tube 15, such connections, however, being no part of I ofgravity'to a coin box or similar receptacle nism, it is to be noted that all of the elements the coin-controlled mechanism 7 proper :and

varying with the type and nature of devices to which said mechanism is applied.

When the coin, under the. influence ofthe, block 38, has actuated the bracket 62 and arm 1 lO'to the upper end-10f ,acoin drop through which said coin descendsunder the influence (not shown) where the-coins are collected until removed byean attendant, thebracket and arm assembly 62-67 returning to normal position by the action of itsunba'lanced weight when the coin has ceased to engagethe disc 63. The complete mechanism may be suitably enclosed in any desired manner, as

by plates 78, and maybe positionedandarranged for practical operation in themanner best' suited to the device or apparatus to be controlled theiethrough. e In the practical operationofthe mechaof the mechanism return or are returned to normal coin-receiving position automatically and are actuated through manual operation of the push-rod 28 and the mechanical events subsequent to such operation, a simple adjustment of the rod 32 permitting closingfof the switch tube 15 directly and without employme'nt of the'coin-control, when desirable. A coin deposited through the coin slotof the plate 11 is tested in its progress through the mechanism for magnetic susceptibility, for hardness,for thickness and for diameter, and the mechanism can readily be so adjusted that only coins successfully meeting these tests will close the circuit through the switch tube 15'and operate the device or apparatus con-. trolled by the mechanism.. j
